I have been all over this forum and all over the namsreviewsandguides site and I am still really confused after so much time.

I would like someone to verify that I have this correct and that the information I cite for part number 53161 on the english shopping site (shop.aquacomputer.de) site is incorrectly worded. That may be the source of the problem.


I think I just need 1 more 3-pin cable (listed below after "what I want to do") but the 3-pin cable on the aquacomputer site says it is a 4-pin cable and has a different number than the 3-pin cable that came with the PA3.

What I want to do:

Connect Via USB and Aquabus the following:

--Aquero 6 XT
--Aquastream Ultimate
--Aqualis Reservoir with fill sensor USB
--2 Poweradjust 3 USB
--1 FarbWerk USB
--1 model 53129 High Flow water meter USB

I planned on connecting it the following way:

1. Aquastream Ultimate connected via USB and AC (Aquacomputer) 3-pin Y adapter #53063 to Aquabus "high" on back of Aquareo 6 XT. The "single" part of the Y is in the back of the Aquareo, splitting its one "high" port). 2 each of AC 3-pin 93111 will be needed for the two "arms" of the Y due to the "gender" issue if I got the picture right.
2. The other half of the Y goes to Poweradjust 3 USB #1 (see question below as to which is port #1 and does it matter in Aquabus) using AC 3-pin cable 93111.
3. Connect the second Aquabus port of PA #1 to PA #2 Aquabus port #1 using AC 3-pin cable 93111.
4. Connect the second Aquabus port of PA #2 to FarbWerk USB Aquabus port #1 using AC 3-pin cable 93111.
5. Connect the second Aquabus port of Farbwerk to the Aqualis flow level aquabus port using the 3-pin cable that came with the Aqualis.
6. Flow sensor is connected directly to the back of the Aquero 6 XT "flow" port (and USB).

I am using Aquabus and USB as Shoggy said in a thread that it makes for "A 4-pin connection cable can be still used for PSU-powered devices and sometimes it helps to prevent strange communication issues between devices. In other words: it is a bit more reliable." He said that about 4-pin Aquabus connections. I am assuming the same holds true with 3-pin connections plus I can controll everything from the Aquaero if for some reason the software is not working, right?

Now to my questions:

1. If I connect everything with USB and Aquabus as I have indicated, am I good?
2. On the Poweradjust and the Farbwerk, are the Aquabus port's interchangeable or is one "master" and one "slave?" I could not find a reference (or I missed it) and I wanted to make sure I cabled it right. If one takes priority, how do you tell?
3. I need a few more model number 93111 cables (came with the PA3USBs) but the only 3-pin cable on the AC shop is model number 53161 which looks like a 3-pin cable but is described as a 4-pin cable and says it supports the Poweradjust 2, not the 3 for Aquabus. I assume those are mistakes.
4. Does anyone know (since I have not received it yet), will the Farbwerk mount between my two AP3 USBs on the 5.25 mounting plate? Or is the FW meant to be mounted with double-sided tape?

Thanks in advanced to anyone who can help me correct any of this.

Here is the page that started the confusion for me:

shop.aquacomputer.de/product_info.php?products_id=3181


part number 53161, Aquabus/RPM signal cable. (3-pin, but the description says 4-pin and it lists only Poweradjust 2 as being supported for Aquabus.


Thank you very much.
